Hi all, I am currently working on an implementation of a new relay environemnt for our Exchange servers. This means that the Postfix machines will do spam / virus / header / whatever checking prior to forwarding it to our Exchange cluster.
The idea was to have two OpenBSD machines with pf + spamd to serve as mail firewall. After that we get postfix + spamassassin + clamav + clamsmtp. Here, postfix reads an hash database generated by postmap to see if the email address is valid. And yes, only the full email address + domain is put in this hash db and nothing else. These are all virtual users, so we don't use any local accounts or whatsoever. After all the checking, we want to use maildrop as filtering language. Here, we want to quarantine spam mails that are tagged by spamassassin to a seperate folder. Also we want to use relaydb to forward the spam email to the mail firewalls (where after spamassassin tagged an X amount of messages as spam from 1 MTA, the sending MTA will be blocked.) However, there is one problem. Since maildrop uses courier-authlib to authenticate, the best possiblity will be to use the postmap generated hash file. But now my question is ... is this possible? I was looking at auth_userdb, but I am not sure if this is able to do what I want. The best option would be that maildrop is not authenticating at all anymore, but I think maildrop always wants to authenticate. This because we only want to use the filtering capabilties of maildrop. I know we can also use Amavis in theory, but we want to use relaydb and possibly other filtering rules and this is not possible with Amavis. We prefer not to use amavis due to upgrade issues we had in the past. I hope my question is clear. I am open for other ideas, of course, but basically the ideal solution would be to have maildrop authenticate against the postmap hash db. Thanks in advance, Jorn P.S: I am not sure if you need to see config files or not, but I don't think you need to. Feel free to ask for them if you need them. ------------------------------------------------------------------------- Take Surveys. Earn Cash.
